				Represents a series of connected line segments, or <i>polyline</i>,
that can be stroked with a configurable color and thickness. Each
articulation point in the line corresponds to a datum; for <i>n</i> points,
<i>n</i>-1 connected line segments are drawn. The point is positioned using
the box model. Arbitrary paths are also possible, allowing radar plots and
other custom visualizations.

<p>Like areas, lines can be stroked and filled with arbitrary colors. In most
cases, lines are only stroked, but the fill style can be used to construct
arbitrary polygons.

<p>See also the <a href="../../api/Line.html">Line guide</a>.
